The Tracerline EZ-Shot R-134a/PAG Dye Injection Kit (TP9793-BX) provides the most accurate and efficient method for adding fluorescent leak detection dye to a vehicle’s R-134a A/C system. This professional-grade kit is designed for both experienced technicians and serious DIY enthusiasts who need a reliable solution for pinpointing refrigerant leaks. The all-in-one system uses a pre-filled, disposable cartridge and a unique caulking gun-style injector to ensure a precise, one-shot dose every time. This eliminates guesswork and potential mess, making the leak detection process faster and cleaner. By servicing multiple vehicles with a single cartridge and a quick connection per system, you can significantly improve your workflow efficiency. The kit’s components are engineered for seamless integration, including a specialized hose/coupler that connects directly to the low-side service port, providing a secure and leak-free experience.
KEY FEATURES AND BENEFITS:
- Most Accurate Method: The caulking gun-style injector allows for a controlled, single-dose injection, ensuring the correct amount of dye is added to the system without waste or over-dosing.
- Highly Efficient: The pre-filled, multi-dose cartridge and single-connection design enable you to service multiple A/C systems quickly, boosting productivity.
- Mess-Free Operation: The self-contained, pre-filled cartridge and injector system eliminates the need for pouring or measuring dye, preventing spills and keeping your workspace clean.
- OEM-Grade Dye: The included fluorescent dye meets or exceeds industry standards, ensuring it is compatible with R-134a/PAG A/C systems and provides clear, bright leak indications under a UV lamp.
- All-in-One Solution: The kit contains everything needed for dye injection, including the injector, a multi-dose dye cartridge, and a specific R-134a hose/coupler, making it a complete and convenient package.
SPECIFICATIONS:
- Included in the kit:
- TP9760-8 BigEZ™ R-134a/PAG Cartridge
- TP-9749 EZ-Shot™ Caulking Gun-Style Dye Injector Assembly
- TP-9793-BX 18” (46 cm) R-134a Hose/Coupler with check valve and purge fitting
HOW TO USE:
- Prepare the Injector: Insert the TP9760-8 BigEZ™ dye cartridge into the TP-9749 EZ-Shot™ injector assembly.
- Connect to the Vehicle: Attach the R-134a hose/coupler to the low-side service port of the vehicle’s A/C system.
- Inject the Dye: Squeeze the trigger on the EZ-Shot™ injector one time to inject a single, precise dose of fluorescent dye into the system.
- Circulate the Dye: Run the vehicle’s A/C system for approximately 15-20 minutes to allow the dye to circulate with the refrigerant and oil.
- Scan for Leaks: Using a UV leak detection lamp (sold separately), scan the A/C system’s components. Any leaks will be visible as a bright, glowing area where the fluorescent dye has escaped.
